Follow the lone pair

Amines are derivatives of ammonia, so nitrogen usually makes three bonds and keeps one lone pair. They are classified as primary, secondary, or tertiary according to how many carbon groups are bonded to nitrogen.
Step-by-step lessons covering Edexcel A Level Chemistry Amines, amides, amino acids and proteins for A Level Chemistry. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
